Hi, I’ve tried to make a rs485 shield for the photon, but I didn’t check if there was any way add a kind of RX/TX led before I ordered the pcbs.
Should this work ?

Hey there–you mean an LED that turns on whenever there is activity over the Rx and Tx line?
That looks right to me, but I’ve only designed a handful of PCBs Note that those are the hardware serial pins, so if you want to see LED activity using USB serial, you’d have to wire those up separately.
Tested by using the continuity with a DMM and found that the connection in between the photon and the LED was faulty
